PL/Sql RESULT_CACHE Function under VPD environment

Hi,
Imagine that I have a VPD environment that depending on the user the data returned from the table in a schema is different than returned to other user. for instance:
The VPD filters the data by company_id in this table
table persons
company_id number(4),
person_id number(4)
person varchar2(100)
now imagine that I connect as scott and scott belongs company_id 1000. If scott runs select * from schema.persons he will see this
1000 123 ANNA
1000 124 MARY
1000 125 SCOTT
If I connect as JOHN and JOHN belongs to company_id 1111. If scott runs select * from schema.persons he will see this
1111 123 ALBERT
1111 124 KEVIN
1111 125 JOHN
This is the VPD environment I have...
So, does RESULT_CACHE functions works well under this type of environment? RESULT_CACHE is shared between sessions... but in this case the sessions of scott and john see always different results. Is there any option of implementing RESULT_CACHE by username?
Regards
Ricardo

It appears that the result cache functionality can work with Virtual Private Database. Check out the following links:

SQL query, function or SP for converting varbinary to image(.jpg format).

Dear Sir/Mam
I want SQL query, function or SP which converts binary data to image (.jpg format).
I m able to convert image (.jpg format) to varbinary. But not able to convert vice versa.
thanks in advance.

Binary data is binary data - "image" is only an intrepretation of binary data. Therefore your question makes little sense in the context of sql server since it does not have any facilities to utilize images. Since you provide no context, I'm
guessing that you are trying to retrieve an image stored in the database in a varbinary column and have your application use it as an image. If so, you should post your question to a forum that is specific to your development environment.

Does a table/view still return records if the underlying VPD policy fails ?

Hi All,
I have one following question -
Does a table or view still return records if the underlying VPD policy fails?
I am adding one more thing here. Let us say security is being implemented using the application context and VPD.
What would happen when application context is not set ? Would the application apply any default privilege as VPD?
Thanks,
Ashi

If you are truly setting a VPD, you have to make sure that the context is set and the condition variable are passed through it. This is normally done through a logon trigger so again, generically , its not possible that it would not be set. I didn't get at all what ever you said in the last line? What is "default priv for VPD" ?

[Q] Login failure under CDE environment

All..
I set up the new SUN UNIX server (SUN v440, SunOS 5.8).
It is set NIS,NFS etc environment and Now I can access the server via telnet, ftp.
However, when I try to access under CDE environment through X-termial (such as Exceed), I cannot log in the UNIX server.
Usually DT login trouble that I met is caused by network trouble.
But in this case, I can connect that UNIX server via telnet, ftp. And network configuration is set correctly.
I have no clue how to solve this trouble.
Would anyone let me know what I should check out or investigate ?
Thanks in advance.

Hi,
Its good that u pasted the complete log file. In your environment you have to run this upgrade tool only once from any of the middle tier.
And with respect to your error that u got in precheck is quite simple. All u have to do is just run this script from by connecting to portal schema using sqlplus.
Run dropupg.sql
Location-------- /raid/product/OraHome_1/upgrade/temp/portal/prechktmp/dropupg.sql
Later you re-run the upgrade tool and let me know the status.
Good luck

Logical Operations in SQL decode function ?

Hi,
Is it possible to do Logical Operations in SQL decode function
like
'>'
'<'
'>='
'<='
'<>'
not in
in
not null
is null
eg...
select col1 ,order_by,decode ( col1 , > 10 , 0 , 1)
from tab;
select col1 ,order_by,decode ( col1 , <> 10 , 0 , 1)
from tab;
select col1 ,order_by,decode ( col1 , not in (10,11,12) , 0 , 1)
from tab;
select col1 ,order_by,decode ( col1 ,is null , 0 , 1)
from tab;

example:
select col1 ,order_by,case when col1 > 10 then 0 else 1 end
from tab;
select col1 ,order_by,case when col1 <> 10 then 0 else 1 end
from tab;
select col1 ,order_by,case when col1 not in (10,11,12) then 0 else 1 end
from tab;As for testing for null, decode handles that by default anyway so you can have decode or case easily..
select col1 ,order_by,decode (col1, null , 0 , 1)
from tab;
select col1 ,order_by,case when col1 is null then 0 else 1 end
from tab;

How to Passing clob to PL/SQL pipeline function

I have a PL/SQL stored function which takes clob as input parameter and sends the results in a pipe line.
create or replace function GetIds(p_list clob, p_del varchar2 := ',') return ideset_t pipelined is
I am using ojdbc14.jar (Oracle 10g driver) with oracle 9i (9.2.0.1.0).
I want to use the following SQL Query select * from table(GetIds(clob))
Now the question is how can I pass the clob from JDBC?
Here is my client code
PreparedStatement stmt = con.prepareStatement("SELECT COLUMN_VALUE FROM TABLE(GETIDS(?, ','))");
stmt.setCharacterStream(1, new StringReader(str), str.length());
stmt.executeQuery();
I get the following error when I try to run the program. The same thing works fine if the chracter lenght is less than some chaaracters.

The setChracterStream works for any insert/update clob. Example when I tried the query (INSERT INTO CLOB_TEST VALUES(?)) setCharacterStream just works fine.
Please any one can help me how to solve this.
Thanks in advance.

HÃ³la LuÃs,
when you pick the PL/SQL function body returning a boolean, it implicitly means that TRUE means OK, while FALSE means error, always.
In order to associate such error to a given form field, you have to go back to the page definiton / validations and specify the name of the item in the corresponding field.
When you first create the validation rule, this value is not present even if you ask for the error message inline with the field.
The error message text can be specified in the validation definition, if I am not wrong.
When you need to return special error messages, including dynamic content for instance, you can use the Function Returning Error Message type, which reports an error when the string returned by the function is not null. This comes in handy when you want to display an item's code, for example, rather than generic text.
Even in this case, you must go back to the validation and specify the name of the field if you want to see it inline.
Hope it helps,
Flavio

It's a common issue. The Basic panel is merely hidden.

How to keep track of EJBs in case of failover under clustered environment?

Does anybody know what happens with a stateless session EJB in
weblogic 5.1 under clustered environment, in case of a failover (if
one of computers dies), the one, which keeps that ejb in a pool?
Does that EJB automatically go to the state "does not exist"?
Is method ejbRemove() then called on that EJB?
Or is it still in the "method-ready pool" state? Without ejbCreate()
method being called on this EJB?
Or does it disappear completely without those methods being called on
this EJB?
I need to organize some kind of tracking for those EJBs, and it is
critically important for me to understand what exactly methods are
called on those EJBs.
I saw this, but it does not answer my question:
Clustered EJB
All EJBs are clusterable. If an EJB is deployed on multiple servers in
the cluster, each of these servers will be able to host instances of
the bean. This does not necessarily mean, however, that the bean
instances are clustered.
EJB Homes
All bean homes are clusterable. When a bean is deployed on a server,
its home is bound into the cluster-wide naming service. Because homes
are clusterable, each server can bind an instance of the home under
the same name. When a client looks up this home, it gets a
replica-aware stub that has a reference to the home on each server
that deployed the bean. When create() or find() is called, the
replica-aware stub routes the call to one of the replicas. The home
replica that receives the finds or creates an instance of the bean on
its server.
Stateless EJBs
When a home creates a stateless bean, it returns a replica-aware stub
that can route to any server on which the bean is deployed. Because a
stateless bean holds no state on behalf of the client, the stub is
free to route any call to any server that hosts the bean. Also,
because the bean is clustered, the stub can automatically fail over in
the event of a failure. The stub does not automatically treat the bean
as idempotent, so it will not recover automatically from all failures.
If the bean has been written with idempotent methods, this can be
noted in the deployment descriptor and automatic fail-over will be
enabled in all cases.
Thanks

Query of queries disallows SQL right() function

We're attempting to do a query of queries using the SQL
right() function like this:
select *
from getresults
where right([key],charindex('\',reverse([key]),1)-1) not in
(#quotedvaluelist(getexcluded.file_name)#)
We've even replaced that where clause with a much more simple
where right([key])='m'
just to make sure that it wasn't the nesting functions that
were causing the problem.
In either case, we get the error:
Query of Queries syntax error.
Encountered "right" at line 0, column 0. Incorrect
conditional expression,
Expected one of [like|null|between|in|comparison] condition,
What SQL functions are disallowed from query of queries?
Thanks,

Nasty stuff huh. Just happened to discover myself today that
Left doesn't work. I'd suspect that Aggregate functions are the
ONLY ones that will work. It would have been nice if they'd at
least allowed CF vs DB functions in their own "database" language.
BTW, also discovered that Count() returns Null rather than 0
when there aren't any per your WHERE clause.

Chart - problem with realize one of the function under CR XI

Post Author: mrowa
CA Forum: Charts and Graphs
Hello,
I have
problem with realize one of the function under CR XI. I would be persuade if
any of us would like to help me.
1)
1) From
database (basically from one table), I take data to make report. Each of record
have appropriate fields:
dteData
intYear
intMonth
intDate
2)
2) I
want to realized comparison data from two or more periods of time on one chart
and in one table. For easily explanation I will describe problem on two
periods.For instance, user want to display and compare
on chart date (type monthly -sum data of each month) from 2007.02 u2013 2007.05
with date from 2006.03 u2013 2006.06. So we compare month 2007.02 with 2006.03;
2007.03 with 2006.04; 2007.04 with 2006.05; 2007.05 with 2006.06
On char I would like to display bars with comparison
of months.
Problem is that I donu2019t know how to write
something similar. I can use one period without any problems, but two and mores
I canu2019t realized.
Detail description:
I passed
two parameters two report:
{?from}, {?to} u2013for first period
{?offset}, it means {?from}+{?offset},
{?to}+{?offset} - for second period
On axis Y I have Sum(intDate);On
X (year + month). But on each value x( example 20007.02) I need to have
two values (bars). Value for standard period and offset.
For example for x=2007.02, I need
two bars one equal 2007.02 and second with offset u2013 2006.03
Movement to next value (bar) is
persuade by fields {data.rok}&{data.month} first or second period. This is
combination of two elements year&month defined under Formula. Problem
persist in that both period has different year.month and here problem starts once
again. I donu2019t know how to solve it. I have found out one solution but it
limits user only for two periods (I want to compare more).
My idea for compare only two
periods:
I make one query in CR for one
period and second query for second period.
Firs query:
"SELECT
       year ,
      month
Second query
"SELECT
       year + FLOOR({month + offset} % 13),
      {month + offset} % 13
Then in CR I connect two periods and
make u201Ctableu201D (results of queries) with JOIN on fields year and month.
This solution is not functional,
because I need to make reports for days and hours as well. In this solution I
canu2019t use (%31), because not all months has 31 days.
I use CR in WEB app made in Visual
Studio 2005. Maybe from aspx we can manipulate with date to get exact solution,
and solve problem with SELECT.
Hope my description clearly
describe problem and someone will be able to help me. I would be thankful.

I have had similar problem before.
Because I had too many data, the legend would not display all the data. Also the chart would not display all the data. But I was able to find a work around.
In your case, Right click on the Legend text and click on Format Legend Entry.
Change the font of the legend to 4 (which is the minimum). This may work.
If you are also having problem with data labels, you could change the font size of the data labels.
Hope this helps.
Thank you.

Problem with SQL Convert Function Junk Character

Hi All,
We have a database field that has a value of “2.020 OPERATOE’S CAB – GLASSES” on the front end of Oracle E-Business Suite. When we are spooling that column(in PLSQL) with the SQL covert function , one of the characters(’) in the string is not getting converted properly. It is displayed as a junk character in the spooled file.
We used CONVERT(p_column,'WE8ISO8859P1','UTF8') for converting the string and utl_file api for spooling the output file. Please note that converted string is passed to utl_file.fopen directly.
Following are the nls_parameters values.
NLS_CHARACTERSET ~~ UTF8
NLS_NCHAR_CHARACTERSET ~~ AL16UTF16
Any inputs are welcome.
Thanks
